Title: Key sharing method and communication equipment
Inventor: CHIN SHISHO
IPC: H04L9/08
Filed: 2002-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To easily change a common key shared by a plurality of pieces of communication equipment.  <P>SOLUTION: N (= four) pieces of communication equipment P1 to P4 trying to share a common key share a prime number q' satisfying 'q'=2q+1' about a prime number q and a primitive element α of a Galois field GF (q'). Each communication equipment Pi (i=1 to 4) has an odd secret key N<SB>i</SB>that is mutually a prime to the prime number q. Each communication equipment Pi broadcasts public data Z<SB>i</SB>generated from an expression (1) as a first step, broadcasts public data X<SB>i</SB>generated from an expression (2) as a second step, broadcasts public data Y<SB>i</SB>generated from an expression (3) as a third step, and generates a common key K from an expression (4) as a fourth step. Thus, the common key K is shared by the communication equipment P1 to P4, and since each communication equipment P1 has public data Y1 to Y4, each communication equipment Pi can easily change the common key K.  <P>COPYRIGHT: (C)2003,JPO

Title: Pachinko game machine
Inventor: UCHIGASHIMA TOSHIHIRO
IPC: A63F7/02
Filed: 2002-03-20
Abstract: PROBLEM TO BE SOLVED: To guarantee the transmission of data from a main control board to each control board when a power supply is turned on. SOLUTION: The security check time T1 of the main control board is not less than security check time T2 of a sub-control board, and the security check operation of the main control board is carried out later than the security check operation of the sub-control board. Consequently, when a CPU of the main control board starts to carry out the control of a game according to a program written in a ROM, each CPU of the sub-control board is already carrying out the control of the game. As a result, even if the CPU of the main control board transmits data to each sub-control board immediately after the power supply is turned on, each sub-control board can positively receive data since it is carrying out the original control.

Filed: 2002-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a digital television broadcast receiver and a video program displaying method which improves serviceability in selection of digital broadcast programs to view.  <P>SOLUTION: The receiver identifies a program broadcast system for programs under broadcasting or recorded in the digital television broadcast according to a specified operation, based on their service IDs, service list descriptors, and component descriptors in program sequence information sent with TS signals, and lists and shows programs to be viewed, related to specified broadcast systems. It displays TV broadcast programs 'SDTV' in a broadcast system 'HDTV' with small scenes of still pictures. When any of them is selected, the receiver starts the receiving operation for the program (the data reading operation for a recorded program) to switch to a moving picture display mode. If the decision operation is made in this condition, the moving picture is zoomed to screen up to a full screen to display the program. Thus, the user can select programs in a desired broadcast system without fail, and simply check the concrete contents of each program.  <P>COPYRIGHT: (C)2004,JPO

Title: Power inverter
Inventor: HANAOKA HIROYUKI
IPC: H02M7/48
Filed: 2002-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a power inverter which can protect a power inverting circuit from an overcurrent, when a switching means of low response speed is used as a switching means in a breaking circuit for preventing an overcurrent from flowing in an input side which is caused by phase difference between an input voltage and an output voltage. SOLUTION: A switching means whose response speed is low as compared with a semiconductor switching element is used in a breaking circuit 2. An overcurrent detecting circuit 3 detects whether an input current is an overcurrent. While the overcurrent detecting circuit 3 detects an overcurrent, a command input obstructing circuit 4 prevents an instantaneous current control signal and an instantaneous voltage control signal from inputting in a drive signal generating circuit 5. When an overcurrent flows for a long term, the breaking circuit 2 operates and a breaking state is set.
